BadAss SRT-Z - 2.4L / A568 - Update!!!

[BadAssPerformance]

JT, while you're at it, you might want to measure the depth of the UD pulley. I'm using an MPx UD pulley and when put on the crank it pushes the crank gear towards the oil pump. I remember beeing it somewhat over 1mm.

took some measurements and indeed the depth of the stock pulley is different. I had to put the UD pulley on the lathe and took a bit off. Fit like charm afterwards.

Interesting. I'm using a ebay knockoff of a Unorthadox one for a 2.4LT PT... I'll look at that

Wow compression is quite a bit lower on the 2.4 over the hybrid ? Or is that from the camshafts mainly ? my hybrid is getting about 185 psi with 2.5 pistons and 2.4 stock cams.

[BadAssPerformance]

Dunno, thats what its always been, even with stock 2.4L cams

[Turbo3Iroc]

Yeah that's about the same compression as a stock TIII also JT. I dont know what 2.5's usually run for compression but 185 sounds high to me.

[glhs0426]

I've seen stock 2.4L's as low as 150, but as high as 200 cranking compression. Most run around 180psi. 2.0L HO's were around 220 when everything was right with the world.

Thats sounds wicked high for a car youre going to throw 20+PSI of boost at. You talking an N/A 2.4 or an SRT??

[turbovanman²]

Bummer about the launch's, at least your getting it sorted out,

Update…

Exhaust leak – header nut was MIA (probably in the left lane?) I’ll put new gasket in tomorrow
Checked compression – 155-152-155-150 – OK
Checked timing – Crank trigger moved… a lot – will fix tomorrow

Good compression numbers.

Yep, mine was 150 when I first rebuilt it.

Cutting it close man... Do you have to run the Z this weekend? Is your registration tied to the Z? Or can you run another car?

[BadAssPerformance]

The registration is tied to me not the car so theoretically I can bring any car... but I'm planning to bring the Z Dunno if I can switch cars for Saturday if there are issues Friday?

[bakes]

You can try and put green locite on the crank snout it might help.

[BadAssPerformance]

I though about that... I welded a bead on the ID and re-ground it.. its a tad tighter now!

Go to Fastenal and purchase the Nord-Lock washers in 5/16" (8mm). They work awesome.

That is some bad@ss sheot right there! We use it at work a lot for high vibration and very fast applications. I went to a loctite training class and they were doing some crazy stuff with the green.

[89ShelbyGuy]

Oh god...the only problem with the green stuff is, if you ever wanna get it back off...ur going to have one hell of a time...i use that stuff all the time..if you apply it right with very clean surfaces, it won't go anywhere ever....

You can usually break it loose with heat...but a lot of application you can't use heat....

[BadAssPerformance]

Hmmm, interesting washers....

[Reeves]

Hmmm, interesting washers....

I used them on Dad's Hemi Charger when I installed the Kooks Long Tube Headers.....so far they have never developed a leak.

I kept having my nuts on the OMNI header coming loose, even with normal lock washers....installed the Nord-Lock last season and so far so good!!!

[BadAssPerformance]

...searching for Fastenal location.

[22shelby]

there is a fastenal, on north ave here in lombard

[BadAssPerformance]

Fastenal couldnt get them fast and I forgo tto get them from McRaceMaster Carr today.. so I just gotta check them between rounds.

Car is all together, catch can added, changed WG signal to the comp housing and added a crapload of timing to the pre-boost high RPM (launch area) to help it get out of the hole… all washed (THANKS DSC! ) and ready to load onthe trailer! ...Then some serious finger crossing till pass #1, LOL…

*crossing fingers*
